高斯消元法的matlab代码

Sure, here's a sample MATLAB code for Gaussian elimination method:

function [x] = gausselim(A, b)

[n, m] = size(A);
aug = [A b];

for i = 1:n-1
pivot = aug(i,i);
for j = i+1:n
factor = aug(j,i)/pivot;
aug(j,:) = aug(j,:) - factor * aug(i,:);
end
end

x = zeros(n,1);
for i = n:-1:1
x(i) = (aug(i,m+1) - aug(i,i+1:n)*x(i+1:n))/aug(i,i);
end

end

Hope this helps!
